Problems solved by technology

[0002] In the geothermal system, because the length of the geothermal well pipe is often relatively long, and the geothermal water drawn is natural water with a large amount of calcium and magnesium ions, it is easy to generate calcium dirt in the well pipe, which will accumulate and block the pipe for a long time
[0003] Descaling is an extremely difficult task. Geothermal well pipes are directly connected to groundwater, and the use of chemicals will pollute groundwater resources. In the existing technology, t

Abstract

The invention provides a descaling device for a geoheat pipe. The descaling device comprises a high-pressure water pump, a connecting pipe, a seal housing, a first motor, a spool, a rope, a fixed block, a rubber jacket and a scraper, wherein the high-pressure water pump communicates with the connecting pipe; the seal housing communicates with and is fixed to the connecting pipe; the first motor isarranged on one side of the seal housing; an output shaft of the first motor hermetically penetrates into the seal housing; the spool is fixed to the output shaft of the first motor; the rope is arranged on the spool; the fixed block is fixed to the rope; and the rubber jacket and the scraper are detachably mounted on the fixed block. According to the descaling device for the geoheat pipe and thedescaling method, the fixed block, the rubber jacket and the scraper are pushed by high-pressure water generated by using the high-pressure water pump to move along the geoheat pipe, and scale on theinner wall of the geoheat pipe is scraped off by the scraper during the moving process of the scraper, and therefore, the operation is simple and labor-saving.

Description

technical field [0001] The invention relates to the field of descaling of thermal pipelines, in particular to a descaling device and method for geothermal pipelines. Background technique [0002] In the geothermal system, because the length of the geothermal well pipe is often relatively long, and the geothermal water drawn is natural water with a large amount of calcium and magnesium ions, it is easy to generate calcium dirt in the well pipe, which accumulates and blocks the pipe for a long time. [0003] Descaling is an extremely difficult task. Geothermal well pipes are directly connected to groundwater, and the use of chemicals will pollute groundwater resources. In the existing technology, there are related tools for deepwater pipeline descaling. For example, the patent number is CN201620753030. 4. CN201821119253.0, these devices for removing dirt from pipelines are all connected by rods. However, once deep wells are involved, the length of the rods is too long, resulti...
